my dad had a supercar but im not sure which

[VIPERICH]

my parents were divorced when i was young.i have not seen or talked to my father in many many years.
the story from my uncles and my mother is that my dad went to new york or upper pa somewhere and brought home a big block nova that he could not even get insured.it was a 4speed and they think it was blue and white.im thinking a motion nova?im picking my mothers brain for more answers as to colors ect.she thinks it was blue with white stripes.
his name was arthur swanson from wilmington delaware.im hoping when i go thrue the tons of slides my mother has that there may be a glimpse ect.ill keep everyone in touch.
anyone have any input on this?
